Star Boy
Star Boy
Thom Kallor, from 30th century Xanthu, was born on a space station where his parents conducted research on the light emitted from celestial stars. This starlight gives Thom the ability to draw mass from the stars and transfer it into any object - making it super-heavy (Adv No. 365, Feb 1968: "Origins and Powers of the Legion of Super-Heroes!").
Star Boy is a member of the Legion of Super-Heroes. He is once suspended for killing in self-defense (Adv No. 342, Mar 1966: "The Legionnaire Who Killed!"), but later is re-admitted to the Legion.
Before acquiring his later powers as Star Boy, Thom experiences the radioactive emissions of a comet's tail and develops powers that are almost identical to those of Superboy. He differs in possessing electrical and infrared vision (instead of heat vision) and X-ray vision that is blocked by copper (rather than lead). At the time, Thom has a Lana Lang-like girlfriend named Zynthia (Adv No. 282, Mar 1961: "Lana Lang and the Legion of Super-Heroes!").
